The suspension of the use of a herbal medicine injection by the Ministry of Health should not be the end of a medical accident, which has already caused three deaths and abnormal reactions in more than 150 patients.

The problematic injection is used to smooth out blood circulation and has been used for years. But with its application to a wider range of vascular diseases, abnormal reactions have been reported frequently, and deaths were reported late last month.

This is not the first time that an injection made of medicinal herbs has caused deaths.
